| Abstract:
In order to rapidly restore the vegetation of the abandoned quarry and improve the ecological and landscape effects, 17 wild plant species with drought and barren soil-tolerance were selected and planted in the abandoned quarry. The adaptability of these species to the adverse conditions and their effects on ecological restoration and landscape improvement were studied. Ultimately species suitable for afforesting the abandoned quarry were selected. The species introduced were maintained for first year and then let alone to grow naturally. The increases in plant height and crown diameter of these species were measured at the end of the first year after planting, and their survival percentage and coverage were evaluated after 3 years. Results showed that Cudrania cochinchinensis (Lour.) Kudo et Masam, Lagerstroemia kweilinensis S.Lee et L. Lau, ined., Cudrania tricuspidata (Carr.) Bur., Delavaya toxocars Fr., Ficus gibbosa Bl., Cipadessa cinerascens (Pell) H.M., Randia spinosa (Thb.) Poir. Pueraria lobata var. Montana (Lour.) Merr. and Bauhinia corymbosa Roxb. were applicable to afforesting the steep and large scale barren cliff, and Indigofera enneaphylla L. and Ficus dikoua Bureau. were suitable for greening the slashed land. | |
